Printing a Pixel on the screen

Is there any way in which i can make a pixel change colour on the screen, wherever the mouse moves? I have tried doing a search for different API, but cant find the change pixel colour.

If you mean on a form or picturebox, then the PSET method will set a single pixel's colour if the DrawWidth property is 1.

If you mean anywhere on the screen, you probably need the SetPixel API function.

Yeah, i tried that, but i think its for .net, and i dont have that! Any ideas for VB without .NET?

It is not only for .net. Have you used an API-function before? Follow this link:SetPixel. There is also a tutorial on API on that site

I have used API B4, can u c anything wrong with this?:

vb:

Private Type POINTAPI
X As Long
Y As Long
End Type

Private Declare Function GetPixel Lib "gdi32" (ByVal hdc As Long, ByVal X As Long, ByVal Y As Long) As Long
Private Declare Function SetPixel Lib "gdi32" (ByVal hdc As Long, ByVal X As Long, ByVal Y As Long, ByVal crColor As Long) As Long

Const Yellow = &HFFFF&

Private Sub Form_Load()
Dim Point As POINTAPI
Me.AutoRedraw = True
Me.ScaleMode = vbPixels
End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
SetPixel Form1.hdc, X, Y, Yellow
End Sub


Nothing happens on a mouse move

This is a quote from Passel in a previous thread.
With AutoRedraw set True, the .hDC property should refer to the .image buffer in memory and you won't pickup an image from the screen.
But if you use GetDC, the DC returned will be the DC refering to the Screen image of the picturebox, regardless of the state of AutoRedraw, so will pickup anything overlaying it's client area.So add
Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
to the declaration
and replace form.hDc by GetDC(form.hwnd) in your code

Quality - That works Perfectly - Cheers for all ur Help Mad Kitten!
